AU Braided AR15/M4 Carbine Length Buffer Spring

Description:

The AU Braided Buffer Spring is a carbine length replacement for AR15/M4 rifles, designed to improve the function and reliability of your AR15/M4 style rifle. Using three independent strands of wire the unique design absorbs energy by allowing the springs to flex separately from each other. This helps displace excess energy which decreases the chance of spring failure, making your rifle more reliable.
